The Infrastructure Layer
for Global Digital Ownership

Abstract

Vision & Mission

The Problem

Traditional financial and ownership systems remain fragmented, expensive, geographically constrained, and operationally inefficient. Existing blockchain systems partially solve these issues but often introduce new constraints including scalability limitations, poor interoperability, weak enterprise tooling, or inadequate infrastructure for RWAs.

The BrainArk Solution

BrainArk provides a full-stack digital ownership infrastructure layer combining every component needed for a complete, self-sustaining blockchain ecosystem.

Blockchain Architecture

BrainArk operates on a custom Hyperledger Besu blockchain architecture using IBFT consensus, optimized for high reliability, stable validator coordination, and EVM compatibility.

BAK — The Native Asset

BAK is the native utility and settlement asset of the BrainArk ecosystem. As the chain's native coin, BAK is not an ERC-20 token — it operates at the protocol level, similar to ETH on Ethereum.

Wallet Compatibility

BrainArk is fully compatible with all major EVM wallet infrastructure. Users can connect to BrainArk DApps, manage assets, participate in staking, and interact with smart contracts without any proprietary wallet software.

• MetaMask (browser extension & mobile)
• Trust Wallet (mobile)
• WalletConnect-enabled wallets
• EVM-compatible browser wallets
• Hardware wallets (Ledger, Trezor via MetaMask)
• Coinbase Wallet and other EVM mobile wallets

Ecosystem Infrastructure

BrainArk Explorer

A public blockchain explorer providing full transaction visibility, wallet monitoring, contract verification, and ecosystem transparency at explorer.brainark.online.

RPC Infrastructure

Public JSON-RPC systems provide network access for wallets, developers, DApps, and integrations at rpc.brainark.online.

Smart Contract Infrastructure

Full EVM smart contract execution compatible with Solidity tooling and Ethereum development standards. Developers can deploy using Hardhat, Foundry, Remix, and all standard Ethereum toolchains.

DApp Infrastructure

BrainArk provides production-grade decentralized applications for asset management, staking, marketplace trading, campaign claims, liquidity access, and EPO participation.

Real World Asset (RWA) Infrastructure

BrainArk is purpose-built as infrastructure for tokenized ownership systems. The RWA layer enables physical and digital assets to be represented on-chain as NFTs backed by BAK collateral.

Core RWA Contracts

Cross-Chain Infrastructure — WBAK Bridge

To expand interoperability and liquidity beyond the BrainArk Chain, BrainArk introduced WBAK (Wrapped BrainArk) and a cross-chain bridge connecting BrainArk Chain with Binance Smart Chain (BSC).

Bridge Flow

Bridge Security

The bridge infrastructure implements multiple operational security controls including transaction verification, treasury validation, transfer event parsing, amount validation, request queue management, file locking systems, serial transaction processing, request timeout protection, and maximum transaction limits. The bridge oracle verifies on-chain transaction authenticity before settlement execution.

Liquidity Infrastructure

BrainArk integrated WBAK liquidity through PancakeSwap V3 on Binance Smart Chain, providing decentralized public market access for WBAK holders.

The liquidity strategy supports market accessibility, trading depth expansion, DeFi integrations, and cross-chain capital movement. BrainArk intends to deepen liquidity across additional decentralized and centralized exchange environments as the ecosystem scales.

Staking Infrastructure

BrainArk provides two distinct staking layers: on-chain BAK staking through the RWA protocol (backing NFT assets), and WBAK staking on BSC for yield generation and ecosystem alignment.

Staking Tiers

RWA BAK Staking

The on-chain RWA staking protocol allows NFT issuers and owners to lock BAK as collateral within assets. Unstaking returns BAK to the owner subject to a protocol fee (3% for assets ≥ 1 BAK, 20% for sub-unit assets), creating a sustainable treasury model.

EPO Infrastructure

BrainArk includes an Early Public Offering (EPO) infrastructure layer allowing participants to acquire BAK using supported assets including USDT, USDC, BNB, and ETH. The EPO operates through EVM-compatible wallet systems with a seamless single-transaction flow.

EPO participation is accessible at dapp.brainark.online — no proprietary software required.

Security Philosophy

BrainArk prioritizes infrastructure reliability, operational transparency, and ecosystem resilience across all protocol layers.

• Validator coordination — IBFT consensus with defined validator set
• Upgradeable smart contracts — All core contracts use non-standard EIP-1967 proxy pattern for controlled upgrades
• Oracle verification — Bridge and marketplace oracles verify on-chain state before settlement
• Treasury controls — Multi-key admin architecture with separate roles for registry, staking, and marketplace operations
• Transaction integrity — Serial bridge processing with queue management and timeout protection
• Smart contract audit trail — All contract deployments and upgrades recorded on the public explorer

Roadmap

Official Infrastructure

All contract addresses are deployed and verifiable on their respective public explorers.

BrainArk Ecosystem Platforms

The BrainArk ecosystem spans multiple purpose-built platforms, each serving a distinct role in the infrastructure layer. All platforms are live, production-grade, and accessible via standard EVM wallets.

Platform Quick Reference

BrainArk Developer API

The BrainArk Developer API provides a standards-compliant HTTP REST interface to the BrainArk RWA blockchain, enabling institutions, fintech platforms, and independent developers to tokenize physical assets, execute marketplace transactions, and query on-chain state without managing a crypto wallet, writing smart-contract code, or paying gas fees directly. All blockchain operations — wallet signing, gas estimation, nonce management, and EVM encoding — are handled server-side by BrainArk's relay infrastructure. Developers interact through the same API patterns used to integrate any modern cloud service.

Every plan includes the full API surface — read, write, marketplace, and webhooks. The API is live at rwa.brainark.online/api/v1. All requests authenticate using an X-API-Key header. API keys are generated instantly from the developer portal. The relay signing key holds only OPERATOR_ROLE on the core contracts — the DEFAULT_ADMIN_ROLE remains on a cold wallet entirely outside the API path.
